This new John Kerry spot is right on the mark:

John Kerry: “The obligation of a Commander in Chief is to keep our country safe. In Iraq, George Bush has overextended our troops and now failed to secure 380 tons of deadly explosives. The kind used for attacks in Iraq, and for terrorist bombings. His Iraq misjudgments put our soldiers at risk, and make our country less secure. And all he offers is more of the same. As President, I’ll bring a fresh start to protect our troops and our nation. I’m John Kerry and I approved this message.”
